Fig; 2'is an enlarged longitudinal elevation partly hroke away illustrating the aiiangemerit of the combination when in position for use. Fig; 3 is a cross section on the line 3-3 of Fig. 2 looking from Eighth left, and Fig. 4 is. anenlargecl longittidihal section of the left hand oi'tien of Fig: 2 shot ing the method of ti -tening up the supportfor the cyliner.

The hearings of the standards 7 and 8 are preferably provided with caps Illa-mi 1:1 which may he opened-by loosening the nuts 12 ancl 13 after which the caps may be thrown open upon the pins 1% and 15. The standards '4" and 8 are also adapted to slide back and fastened thereto after adjustment they arekeyecl as shown;
